BENJAMIN LEVI, OF NEW YORK, N. Y.

WASHING AND DRYING MACHINE.

Specification of Letters Patent.

Patented July 4, 1916.

Application filed April 24, 1913. Serial No. 763,289.

To all whom it may concern Be it known that I, BENJAMIN LEVI, a citizenof the United States, and a resident of New York, county and State ofNew York, have invented new and useful Improvements in Washing andDrying Machines, of which the'following is a specification.

The main features of this machine for Washing and drying sheet materialconsist of a section of a continuous paper carrier consisting of aconveyer upon which the washing is done and which is composed of narrowbelts substantially horizontally arranged, with their edges contiguous,thus forming an unbroken surface for the material, generally paper,which when wet is apt to sag and catch between the adjacent edges of thenarrow belts forming such conveyers as are now in use; and an inclinesection of the belt conveyer which receives the material from thewashing section of the conveyer; an open face heater for directingheated air to the material on the inclined section of the conveyer; aheated drum which receives the material from the inclined section of theconveyer; a holding belt or apron partly surrounding the drum; and anair blast producing device, as a fan, for directing the leading end ofthe material from the inclined section of the conveyer to the entrancebetween the drum and its apron. These parts with other detail featuresof construction will be fully understood by reference had to theaccompanying drawings, in which:

Figure 1 is a verticallongitudinal section of a machine embodying theessential features of this invention, the frame holding the variousparts being omitted. Fig. 2 is anenlarged plan view of a portion of themachine, with the preliminary heater and the drum apron removed, andFig. 3' is a vertical transverse section on line 3, 3, Fig. 1,

showing a portion of the Washing belt bed 'guider rollers.

The washing section of the belt conveyer is composed of narrow belts aand 6 arranged with their edges close together or in contact, said beltsbeing carried by rollers c, d, and 6;

all of the belts pass around the roller 0, and r the alternate sets ofbelts a and 6 pass around the rollers (11 and 6 respectively.Conveniently arranged to act on the underruns of this belt conveyer aretwo sets of guide rollers f and g of the same width as the narrow beltsa and b and they are carried on the shafts i1. and 71 respectively,arranged so that the rollers of one set will extend in the spaces of theother set, said spaces ofcourse being equal to the widths of the narrowbelts, thus providing perfect guides for said belts, insuring theirproper action on the carrying rollers to constitute a traveling washingbed of continuous surface, without gaps between the belts ofwhich it iscomposed. As shown the upper guide rollers f press one set of belts, asbelts or, downwardly the other set of alternate belts b passing throughthe spaces between the rollers f.

A tank y' located beneath the conveyer a, 6,. contains the washing fluidor water, which by a suitable pump 70 is through the pipe Z carried tothe sprinkling device m, composed of the requisite number of perforatedpipes arranged above the conveyor to thoroughly spray all parts of thesheet material placed thereon. Beneath the conveyer is a trough narranged to direct all drippings back to the tank j. For the finalwashing of the sheet material a fresh water sprinkler 0 is provided, thewater from which also, after acting on the material passes to the tankj. The washing fluid'by continual use would become saturated with thechemicals washed from the sheet material, when such is chemically.prepared,

but the addition of the fresh washing water terial as it is carriedupwardly on the inclined section of the belt conveyer from thehorizontal washing section of the conveyer. The heater r is providedwith a wire netting front 25 to prevent any paper material being treatedfrom entering the heater and sobeing a source of danger if gas flames,as shown, be used for heating purposes.

The upwardly extending conveyer section 8 is composed of two sets ofnarrow belts. One set comprising alternate belts pass over the roller 6and the other set of intervening belts pass over the roller u. Therollers (Z, 6, u are provided with gears and are caused to run in unisonby the intermediate gear wheels 2;, one of which may be provided with adriving pulley 'w. The roller 6 is common to one set of belts of each ofthe section a- Z) and s of the conveyer. This organization is such thatthere is a continuity in the operative connection of the variousdevices, which individually show novelty over the citations and whichcollectively perform special functions in a novel manner. This method ofoperating the sections of belt conveyers is described and claimed inUnited States Letters Patent Number 1,052,007, issued to me February 4,1913.

The upper end of the section 8 of the conveyer is carried on a roller 0:in close proximity to a drying drum 3 the heat of which may be suppliedby a gas burner 2 extending in the interior of the drum through a hollowbearing.

Extending partly around the drying drum y is a belt or apron 1 whichpasses around the roller 2 located beneath the drum and over guiderollers 3, 3, one of which is close to the drum near the roller :0 ofthe conveyer s, and a portion of this apron is in front of the conveyers and extends down close to the heater 7, so heat arising therefrom willbe directed toward the conveyer s. The roller 2 and drum 3 are connectedby gear wheels, and this roller is also connected to the driving pulleyw by suitable gearing, as sprocket wheels and a chain 4:, thearrangement being such that the peripheral speed of the drum willslightly exceed that of the section 8 of the belt conveyer.

The paper or other material is delivered from the section 8 to the drum,and when in the formof sheets there is sometimes a liability for theleading edge of a sheet to adhere to the conveyer section instead ofpassing to the bite of'the drum and the apron. To guard against this agentle blast of air is caused to play toward the roller :0 being guidedby a plate 5 adjacent to the conveyer and a curved plate 6; this plate 6also acts to discharge the material from the drum. This air blast may beproduced by any suitable means, as a small electrically driven fan 7.

vent the paper,"particularly when in the form of a long strip, movingany great distance away from the carrier, thus insuring the properconveyance of the paper when such tendency of the paper to leave thecarrier exists. The part or section a, Z), of the paper carrier providesa horizontal table upon which the material may be conveniently fed andthe inclined section or conveyer s properly presents the material to thedrying drum.

It has been found that in treating some kinds of paper fine creases ormarkings due to washing will show when it leaves the drying drum, andall such marks may be eliminated by a spring actuated roller 9 pressingon the apron to produce an ironing effect on the material as it passesbetween the apron and drum beneath said roller.

I claim:

1. A machine of the character described, comprising a heated drum, anendless apron partly surrounding the drum, means for grinding andcontrolling the apron, an inclined paper conveyer with itsdischarge endadjacent the drum near the entrance between the drum and apron, a guideplate extending downwardly at the rear side of the paper conveyer fordirecting the paper away from the drum at the point where the apronleaves the drum, and means for pro ducing an air blast upwardly betweenthe paper carrier and the guide plate.

2.
